    Hello,

    Are you having a problem seeing all of the lines in some of your email from Facebook?

    According to Markus Stumpf on the qmail mailing list:

    Facebook is sending their mails as
    Content-Transfer-Encoding: quoted-printable
    Content-Type: text/plain; charset="UTF-8"

    Despite the fact that RFC2045 clearly states:

    (Soft Line Breaks) The Quoted-Printable encoding REQUIRES that
    encoded lines be no more than 76 characters long. If longer
    lines are to be encoded with the Quoted-Printable encoding,
    "soft" line breaks must be used. An equal sign as the last
    character on a encoded line indicates such a non-significant
    ("soft") line break in the encoded text.

    They are sending lines with some 100 chars wide.

    This leads to some (correct) mail clients truncating lines and displaying garbled messages/text.

    Also - as spammers make the same mistake rather often - I've seen line
    length checks for Quoted-Printable implemented in antispam software.

    I have notified Facebook, but don't expect something to happen. This was the answer:
